Definitions
- the invention relates to a winding shaft or a chuck according to the preamble of independent claim 1, see. DE-A-35 33 735.
- a known winding shaft of this type has a push rod which extends essentially over the entire length of the support tube and which is pneumatically displaced to release the clamping jaws against the counterforce acting in the longitudinal direction of the tension springs.
- the tension force of several springs must be overcome at the same time when the push rod is being moved, which is why at least two pressure chambers are necessary here, which are arranged in the support tube at one end of the winding shaft.
- the result of these pressure spaces is that the winding shaft is considerably longer than the available working width.
- the winding shaft is considerably longer than the available working width.
- each clamping jaw is assigned two clamping wedges which are symmetrical to one another are cocked and between which a pressure chamber is provided to relax the jaw.
- the clamping wedges thus arranged in pairs are each loosened by the clamping wedges which are symmetrically assigned to one another.
- a push rod and the threaded bores in the supporting tube necessary for fastening stops are not required in the winding shaft according to the invention. Since the pressure chambers are not arranged at one end of the winding shaft but rather in the area of the clamping jaws, the working area is not limited by these pressure chambers.
- the working width can therefore be substantially the same as the total length even with very long winding shafts.
- the tension springs are supported on the rod arranged in the support tube and the tensioning wedges are mounted thereon.
- the rod consists of individual segments which are detachably connected to one another.
- a jaw can be assigned to each segment. Since each bar can be put together with the same segments, the storage is considerably simplified.
- the rod has a channel through which compressed air can be supplied from outside to the pressure spaces for displacing the clamping wedges and through which these spaces can be relaxed accordingly.
- the wedge surfaces of the clamping wedges are self-locking and have an inclination angle of, for example, 8 °. This means that a pressure of 6 tons on the clamping jaws is also possible with conventional tension springs.
- a particularly advantageous embodiment of the pressure chambers is achieved if they have a sleeve, which are each held in a recess in a clamping jaw and in which two clamping wedges are inserted.
- the winding shaft has a continuously hollow support tube 1, on which a bearing pin 11 is placed at each end.
- These pins 11 are each with a grub screw 12 fixed on the support tube 1 and serve to support the winding shaft in a known unwinding or reeling device.
- clamping jaws 3 are inserted, which can be displaced radially outward with one or more winding sleeves 15 with clamping wedges 4.
- retaining plates 10 are releasably attached to the supporting tube 1 with countersunk screws 10b, on which pressure springs 10a engaging in bores 3b of the clamping jaws 3 are attached.
- the clamping jaws are pressed inwards when relaxing.
- the clamping jaws 3 can only be moved radially outwards to a limited extent, since they are in an end position when clamping on the holding plates 10.
- Each three clamping jaws 3 distributed symmetrically on the circumference of the support tube 1 form a clamping element 2 with two symmetrically arranged clamping wedges 4, a pressure chamber 6, a rod segment 9a and two likewise symmetrically arranged tension springs 7.
- the rod segments 9a are connected to one another by a connecting sleeve 9c and this is connected at its ends with connecting sleeves 9e to the bearing pins 11.
- the rod has a channel 13 which, in the case of a bearing journal, leads to the outside to a pressure container 14 or a pressure pump and which is connected to the pressure chambers 6 via radial bores 9f.
- two counter-tensioning springs 7 are placed on each rod segment 9a, each of which is supported on the one hand on a clamping wedge 4 and on a stop ring 9d of the corresponding rod segment 9a.
- the two tension springs 7 of a tensioning element 2 tension two tensioning wedges 4, which are slidably guided on the corresponding rod segment 9a, against one another with the same force.
- the clamping forces of the springs 7 are transmitted via wedge surfaces 3a and 4a into radial forces acting on the clamping jaw 3. Two tension springs 7 thus press three jaws 3 against the inside of the winding tube 15.
- the inclination of the wedge surfaces 3a and 4a is designed such that they are self-locking, and therefore counteracting forces of the winding tube 15 cannot be transmitted in longitudinal displacements of the clamping wedges 4.
- a suitable angle of inclination is approximately 8 °.
- the wedge surface 3a is preferably not flat, but has a radius R of 2 m shown in FIG. 1. As a result, better power transmission is achieved even with comparatively high manufacturing tolerances.
- For balancing 3 holes 16 are provided in the jaws made of aluminum, in which steel pins 17 are inserted. The shaft can thus be precisely balanced over its entire length.
- each tensioning element 2 has a pressure chamber 6, which is formed by two tensioning wedges 4, a sleeve 5 and a rod element 9a.
- Each pressure chamber 6 is sealed to the outside with seals 9d and 9e and connected to the channel 13 of the rod 9 via radial bores 9f. If the pressure in the chamber 6 is increased, the clamping wedges 4 are moved outwards in opposite directions in the longitudinal direction against the clamping force of the springs 7, as a result of which the tension on the clamping jaws 3 is reduced.
- the sleeves 5 are each held in recesses 3c of the jaws 3. These recesses 3c also form stops for the clamping wedges 4. The clamping wedges 4 can thus be displaced in the longitudinal direction to a limited extent.
- the pressure in the chambers 6 is reduced, whereupon the clamping springs 7 each move the two clamping wedges 4 of the clamping elements 2 against each other in the longitudinal direction and the clamping jaws 3 radially outwards.
- clamping elements 2 can thus consist of the same parts and only the number of these clamping elements 2 varies according to the length of the winding shaft, the manufacture and maintenance can be significantly simplified. It is essential that the sleeves are clamped centrally, which is optimally achieved with three symmetrically arranged jaws 3 per clamping element 2.
- the winding shaft can also be designed as a tensioning head which is supported or driven only at one end and which can have one or more tensioning elements 2. Otherwise, the statements made with regard to FIGS. 1 and 2 apply here.
Description
Die Erfindung betrifft eine Wickelwelle oder ein Spannkopf nach dem Oberbegriff des unabhängigen Patentanspruchs 1, s. DE-A-35 33 735.The invention relates to a winding shaft or a chuck according to the preamble of
Eine bekannte Wickelwelle dieser Gattung weist eine sich im wesentlichen über die ganze Länge des Tragrohres erstreckende Schubstange auf, die zum Lösen der Spannbacken gegen die in Längsrichtung wirkende Gegenkraft der Spannfedern pneumatisch verschoben wird. Bei langen Wickelwellen muss die Spannkraft mehrerer Federn gleichzeitig beim Verschieben der Schubstange überwunden werden, weshalb hier wenigstens zwei Druckräume notwendig sind, die im Tragrohr an einem Ende der Wickelwelle angeordnet sind. Diese Druckräume haben zur Folge, dass die Wickelwelle wesentlich länger ist als die zur Verfügung stehende Arbeitsbreite. Insbesondere bei schnell rotierenden Hochleistungswickelwellen ist jedoch eine möglichst kurze Ausführung anzustreben, da mit abnehmender Länge bei kleinem Gewicht die robustere erhöht und ein ruhigerer Lauf möglich ist. Lange Wickelwellen dieser Gattung weisen somit verglichen mit der verfügbaren Arbeitsbreite besonders bei hohen Drehzahlen ungünstige Werte auf. Eine weitere Schwierigkeit besteht darin, dass Revisionsarbeiten und der Austausch von Verschleissteilen vergleichsweise schwierig und aufwendig ist. Im Tragrohr sind zahlreiche Gewindebohrungen für Stifte erforderlich, weshalb eine Revision ohne Beschädigung der im Tragrohr angeordneten Dichtungen kaum möglich ist.A known winding shaft of this type has a push rod which extends essentially over the entire length of the support tube and which is pneumatically displaced to release the clamping jaws against the counterforce acting in the longitudinal direction of the tension springs. In the case of long winding shafts, the tension force of several springs must be overcome at the same time when the push rod is being moved, which is why at least two pressure chambers are necessary here, which are arranged in the support tube at one end of the winding shaft. The result of these pressure spaces is that the winding shaft is considerably longer than the available working width. However, especially in the case of rapidly rotating high-performance winding shafts to be as short as possible, since the shorter the longer, the more robust it increases, and a smoother run is possible. Long winding shafts of this type therefore have unfavorable values compared to the available working width, especially at high speeds. Another difficulty is that revision work and the replacement of wear parts is comparatively difficult and complex. Numerous threaded holes for pins are required in the support tube, which is why a revision is hardly possible without damaging the seals arranged in the support tube.
Weitere ähnliche Wickelwellen sind im Sonderdruck aus COATING 7/88 (Autor: H. Klein) beschrieben. Die gattungsgemässe Wickelwelle besitzt trotz den oben genannten Schwierigkeiten gegenüber den in diesem Artikel beschriebenen Wickelwellen bekannte Vorteile. Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Wickelwelle der genannten Gattung zu schaffen, welche die oben genannten Schwierigkeiten vermeidet und die bei niedrigeren Herstellungskosten ein besseres Verhältnis der Gesamtlänge zur Arbeitsbreite besitzt. Die Aufgabe wird durch die Erfindung gemäss Anspruch 1 gelöst.Other similar winding shafts are described in the special print from COATING 7/88 (author: H. Klein). The generic winding shaft has known advantages over the winding shafts described in this article, despite the difficulties mentioned above. The invention is therefore based on the object of providing a winding shaft of the type mentioned which avoids the difficulties mentioned above and which has a better ratio of the total length to the working width at lower production costs. The object is achieved by the invention according to
Bei der erfindungsgemässen Wickelwelle sind jeder Spannbacke zwei Spannkeile zugeordnet, die symmetrisch gegeneinander gespannt sind und zwischen denen eine Druckkammer zum Entspannen der Spannbacke vorgesehen ist. Die somit paarweise angeordneten Spannkeile werden jeweils durch die zwischen den einander symmetrisch zugeordneten Spannkeilen gelöst. Eine Schubstange und die zur Befestigung von Anschlägen notwendigen Gewindebohrungen im Tragrohr sind bei der erfindungsgemässen Wickelwelle nicht erforderlich. Da die Druckkammern nicht an einem Ende der Wickelwelle sondern jeweils im Bereich der Spannbacken angeordnet sind, ist der Arbeitsbereich durch diese Druckkammern nicht beschränkt. Die Arbeitsbreite kann deshalb auch bei sehr langen Wickelwellen im wesentlichen gleich der Gesamtlänge sein.In the winding shaft according to the invention, each clamping jaw is assigned two clamping wedges which are symmetrical to one another are cocked and between which a pressure chamber is provided to relax the jaw. The clamping wedges thus arranged in pairs are each loosened by the clamping wedges which are symmetrically assigned to one another. A push rod and the threaded bores in the supporting tube necessary for fastening stops are not required in the winding shaft according to the invention. Since the pressure chambers are not arranged at one end of the winding shaft but rather in the area of the clamping jaws, the working area is not limited by these pressure chambers. The working width can therefore be substantially the same as the total length even with very long winding shafts.
Eine wesentliche konstruktive Vereinfachung wird erreicht, wenn die Spannfedern an der im Tragrohr angeordneten Stange abgestützt und auf dieser die Spannkeile gelagert sind. Für die Herstellung und die Wartung ist es besonders vorteilhaft, wenn die Stange aus einzelnen lösbar miteinander verbundenen Segmenten besteht. Jedem Segment kann eine Spannbacke zugeordnet werden. Da mit gleichen Segmenten jede Stange zusammengestellt werden kann, wird die Lagerhaltung wesentlich vereinfacht.A significant design simplification is achieved if the tension springs are supported on the rod arranged in the support tube and the tensioning wedges are mounted thereon. For production and maintenance, it is particularly advantageous if the rod consists of individual segments which are detachably connected to one another. A jaw can be assigned to each segment. Since each bar can be put together with the same segments, the storage is considerably simplified.
Nach einer Weiterbildung der Erfindung weist die Stange einen Kanal auf, durch den von aussen den Druckräumen zur Verschiebung der Spannkeile Druckluft zuführbar ist und durch den diese Räume entsprechend entspannt werden können.According to a development of the invention, the rod has a channel through which compressed air can be supplied from outside to the pressure spaces for displacing the clamping wedges and through which these spaces can be relaxed accordingly.
Nach einer anderen Weiterbildung der Erfindung sind die Keilflächen der Spannkeile selbsthemmend und besitzen dazu einen Neigungswinkel von beispielsweise 8°. Damit ist auch mit üblichen Spannfedern ein Druck von 6 Tonnen auf die Spannbacken möglich.According to another development of the invention, the wedge surfaces of the clamping wedges are self-locking and have an inclination angle of, for example, 8 °. This means that a pressure of 6 tons on the clamping jaws is also possible with conventional tension springs.
Eine besonders vorteilhafte Ausbildung der Druckräume wird dann erreicht, wenn diese eine Hülse aufweisen, die jeweils in einer Ausnehmung einer Spannbacke gehalten sind und in die jeweils zwei Spannkeile eingesetzt sind.A particularly advantageous embodiment of the pressure chambers is achieved if they have a sleeve, which are each held in a recess in a clamping jaw and in which two clamping wedges are inserted.
Weitere vorteilhafte Merkmale ergeben sich aus den übrigen Ansprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:
- Fig. 1
- einen Längsschnitt durch einen Abschnitt einer erfindungsgemässen Wickelwelle, und
- Fig. 2
- einen Querschnitt entlang der Linie II - II der Fig. 1.
- Fig. 1
- a longitudinal section through a portion of a winding shaft according to the invention, and
- Fig. 2
- a cross-section along the line II - II of FIG. 1st
Wie die Fig. 1 und 2 zeigen, weist die Wickelwelle ein durchgehend hohles Tragrohr 1 auf, auf das an jedem Ende ein Lagerzapfen 11 aufgesetzt ist. Diese Zapfen 11 sind jeweils mit einem Gewindestift 12 am Tragrohr 1 fixiert und dienen zur Lagerung der Wickelwelle in einer bekannten Abroll- bzw. Aufrolleinrichtung.1 and 2 show, the winding shaft has a continuously
In das Tragrohr 1 sind mehrere Schlitze 1b eingearbeitet, in welche Spannbacken 3 eingesetzt sind, die zur Fixierung einer oder mehrerer Wickelhülsen 15 mit Spannkeilen 4 radial nach aussen verschiebbar sind. Zur Halterung und Führung der Spannbacken 3 sind mit Senkschrauben 10b am Tragrohr 1 Halteplatten 10 lösbar befestigt, an denen in Bohrungen 3b der Spannbacken 3 eingreifende Druckfedern 10a angebracht sind. Durch diese Federn 10a werden die Spannbacken beim Entspannen nach innen gedrückt. Die Spannbacken 3 können nur begrenzt radial nach aussen bewegt werden, da sie beim Spannen an den Halteplatten 10 in einer Endstellung anstehen.In the
Jeweils drei am Umfang des Tragrohres 1 symmetrisch verteilte Spannbacken 3 bilden mit zwei symmetrisch angeordneten Klemmkeilen 4, einer Druckkammer 6, einem Stangensegment 9a sowie zwei ebenfalls symmetrisch angeordneten Spannfedern 7 ein Spannelement 2. Mit Verbindungshülsen 9c sind die Stangensegmente 9a zu einer Stange 9 miteinander verbunden und diese ist an ihren Enden mit Verbindungshülsen 9e mit den Lagerzapfen 11 verbunden. Die Stange weist einen Kanal 13 auf, der bei einem Lagerzapfen nach aussen zu einem Druckbehälter 14 oder einer Druckpumpe führt und der über radiale Bohrungen 9f mit den Druckkammern 6 verbunden ist.Each three
Um die Spannbacken 3 radial nach aussen gegen die Innenseite der Wickelhülse 15 zu spannen, sind auf jedes Stangensegment 9a zwei gegeneinander gerichtete Spannfedern 7 aufgesetzt, die einerseits jeweils an einem Spannkeil 4 und an einem Anschlagring 9d des entsprechenden Stangensegmentes 9a abgestützt sind. Die beiden Spannfedern 7 eines Spannelementes 2 spannen zwei Spannkeile 4, die auf dem entsprechenden Stangensegment 9a gleitverschiebbar geführt sind, mit gleicher Kraft gegeneinander. Die Spannkräfte der Federn 7 werden über Keilflächen 3a und 4a in radiale, auf die Spannbacke 3 wirkende Kräfte übertragen. Zwei Spannfedern 7 drücken somit drei Spannbacken 3 gegen die Innenseite der Wickelhülse 15.In order to clamp the
Die Neigung der Keilflächen 3a und 4a ist so ausgelegt, dass diese selbsthemmend sind, und somit gegenwirkende Kräfte der Wickelhülse 15 nicht in Längsverschiebungen der Spannkeile 4 übertragen werden können. Ein geeigneter Neigungswinkel beträgt etwa 8°. Die Keilfläche 3a ist vorzugsweise nicht eben, sondern weist einen in Fig. 1 gezeigten Radius R von 2 m auf. Dadurch wird eine bessere Kräfteübertragung auch bei vergleichsweise hohen Fertigungstoleranzen erreicht. Zur Auswuchtung sind in den aus Aluminium hergestellten Spannbacken 3 Bohrungen 16 vorgesehen, in die Stahlstifte 17 eingesetzt sind. Die Welle kann damit über ihre ganze Länge exakt ausgewuchtet werden.The inclination of the
Zum Entspannen der Wickelwelle weist jedes Spannelement 2 eine Druckkammer 6 auf, die durch zwei Spannkeile 4 eine Hülse 5 und ein Stangenelement 9a gebildet ist. Mit Dichtungen 9d und 9e ist jede Druckkammer 6 nach aussen abgedichtet und über Radialbohrungen 9f mit dem Kanal 13 der Stange 9 verbunden. Wird in der Kammer 6 der Druck erhöht, so werden die Spannkeile 4 gegen die Spannkraft der Federn 7 in entgegengesetzten Richtungen in Längsrichtung nach aussen bewegt, wodurch die Spannung auf die Spannbacken 3 verringert wird. Wie ersichtlich sind die Hülsen 5 jeweils in Ausnehmungen 3c der Spannbacken 3 gehalten. Diese Ausnehmungen 3c bilden zugleich Anschläge für die Spannkeile 4. Die Spannkeile 4 sind somit begrenzt in Längsrichtung verschiebbar.To relax the winding shaft, each tensioning element 2 has a
Zum Spannen wird der Druck in den Kammern 6 erniedrigt, worauf die Spannfedern 7 jeweils die beiden Spannkeile 4 der Spannelemente 2 in Längsrichtung gegeneinander und die Spannbacken 3 radial nach aussen bewegt.For clamping, the pressure in the
Da alle Spannelemente 2 somit aus gleichen Teilen bestehen können und lediglich die Anzahl dieser Spannelemente 2 entsprechend der Länge der Wickelwelle variiert, kann die Herstellung und die Wartung wesentlich vereinfacht werden. Wesentlich ist, dass die Hülsen zentrisch gespannt werden, was optimal mit drei symmetrisch angeordneten Backen 3 pro Spannelement 2 erreicht wird.Since all clamping elements 2 can thus consist of the same parts and only the number of these clamping elements 2 varies according to the length of the winding shaft, the manufacture and maintenance can be significantly simplified. It is essential that the sleeves are clamped centrally, which is optimally achieved with three symmetrically arranged
Die Wickelwelle kann ebenfalls als Spannkopf ausgeführt sein, der lediglich an einem Ende gelagert oder angetrieben ist und der ein oder mehrere Spannelemente 2 aufweisen kann. Im übrigen gelten hier die bezüglich der Fig. 1 und 2 gemachten Angaben.The winding shaft can also be designed as a tensioning head which is supported or driven only at one end and which can have one or more tensioning elements 2. Otherwise, the statements made with regard to FIGS. 1 and 2 apply here.
Aus den obigen Angaben ergibt sich somit eine Wickelwelle oder ein Spannkopf, der trotz der erheblichen Vorteile ersichtlich mit verhältnismässig wenigen, einfachen und robusten Bauteilen realisierbar ist, so dass erfindungsgemäss eine Wickelwelle oder ein Spannkopf geschaffen wurde, welcher nicht nur den technischen Anforderungen in hervorragender Weise Rechnung trägt, sondern aufgrund seiner konstruktiv einfachen und robusten Ausführbarkeit in der Herstellung günstig und im Betrieb äusserst zuverlässig ist.The above information thus results in a winding shaft or a tensioning head which, despite the considerable advantages, can be realized with relatively few, simple and robust components, so that, according to the invention, a winding shaft or a tensioning head was created which not only meets the technical requirements in an outstanding manner Takes into account, but is due to its structurally simple and robust feasibility to manufacture inexpensive and extremely reliable in operation.
